Title: Learning control system
Inventor: NAKAMURA YUJI
IPC: G05B19/4155
Filed: 1988-11-22
Abstract: PURPOSE:To improve convergence and stability by using subsequent deviation for the delay quantity of an object to be controlled at the time of using preceding control deviation, averaging and using it for the quantity of several steps. CONSTITUTION:A control input uk(i) at a sampling time (i) in a k-numbered trial is given in an expression I. Here, ek(i) is control deviation at the time (i) in the k-numbered trial, sigmak(i) is a correction quantity at the time (i) in the k-numbered trial and g1, g2 and C1-CN are appropriate positive constant. Namely, the control input uk(i) is obtained by weighting and adding deviation ek(i) and a correction quantity sigmak(i). The correction quantity sigmak(i) at the time (i) in the present trial is obtained by adding the mean value of several future values in control deviation in the preceding trial to the correction quantity sigmak(i) at the time (i) in the preceding trial. Thus, it comes to be unnecessary to obtain the transmission function of the object to be controlled since the delay of the object to be controlled is considered, and convergence and stability improve.

Title: Method for obtaining hybridoma of yeast
Inventor: NAKATOMI YASUO
IPC: C12N15/02
Filed: 1992-10-09
Abstract: PURPOSE:To obtain by a simple method a hybridoma produced by hybridizing an easily inducible respiration-deficient strain with a respiration-normal wild type strain. CONSTITUTION:This method for obtaining the hybridoma is characterized by hybridizing a respiration-deficient intersex strain with a respiration-normal wild type strain by a rare-mating method or a cell fusion method, collecting the hybridized strain, and subsequently identifying and separating the hybridized strain. Since the wild type strain can be used for the hybridization of the respiration-deficient strain and since a mutation treatment for introducing an auxotrophic maker, etc., is not required, the denaturation and deterioration of the practical properties of the stain by the mutation treatment is not generated. Since an arbitrary wild type strain can be used as a parent strain for the hybridization, the range of the breeding is spread.
